I have a WLC 4402 Wireless LAN Controller with multiple 1131 AP on LWAPP. WLAN has security setting on WPA+WPA2 with PSK share key. All computers in domain are fine, wireless connections are steady. I have a group of students use Netbook on Windows XP Home SP3 got connection and drop situation. Syetem event log on XP has continuous 4201 and 4202 cases, and on WLC it also has continuous log as
*Apr 19 10:35:44.046: %DOT1X-3-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:407 Max EAPOL-key M1 retransmissions exceeded for client 00:26:5e:eb:fd:0a
Base on Cisco error message bank, the explanation as following:
Error Message %DOT1X-3-MAX_EAPOL_KEY_RETRANS: Max EAPOL-key M[int] retransmissions exceeded for client [hex]:[hex]:[hex]:[hex]:[hex]:[hex]
Explanation Client authentication failed because the client did not respond to an EAPOL-key message.
Recommended Action Ensure that user credentials are correct on the client and on the AAA server.
I understand XP Home has no certificate from Domain environment therefore I didn't setup any AAA server service. How can this problem be resolved? Keep trying on security combination, but no luck. Please Help. Thanks.
